- pKₐ values of catalytic groups from V/K profiles.
- Thermodynamic parameters from temperature dependence.
Segel emphasizes that understanding kinetic behavior provides essential clues to an enzyme’s physiological role. His approach relies on several key pillars: Mohanlal Sukhadia University - Udaipur Enzyme Parameters and Michaelis-Menten Plots - Sketchy Segel Enzyme Kinetics Pdf

(Maximum Velocity): This is the theoretical limit of the reaction rate when all enzyme active sites are saturated with substrate. It depends on the total concentration of enzyme ( ) and the catalytic rate constant ( kcatk sub c a t end-sub ), often called the turnover number: Kmcap K sub m (Michaelis Constant): Kmcap K sub m pKₐ values of catalytic groups from V/K profiles
- Lineweaver-Burk Plot (Double Reciprocal): $1/v$ vs $1/[S]$. Segel highlights that while this is the most common plot, it is statistically flawed because it heavily weights error at low substrate concentrations.
- Eadie-Hofstee Plot: $v$ vs $v/[S]$. This plot distributes error more evenly.
- Hanes-Woolf Plot: $[S]/v$ vs $[S]$. Often recommended by Segel as having the least statistical distortion of the linear methods.
